Specification of Letters Patent.

Patented Sept..9,1913.

Application filed August 1S, 1910. Sera1,N0 577,838,

ental 'Knotted Fabrics, of which ,the following description, in connection with the accompanying drawings, is a specification, like letters on vthe drawings representing like ,parts Thelobject of my invention is to produce a loom `which Will weave an oriental rug, carpet, or other oriental knotted fabric with extreme rapidity and efficiency, Vand which, besides heilig simple in itsknotting mechanism and certain in its knotting and Weaving movements, is capable Aof handling a practically unlimited number of colors, preferably after the manner of Axminstey and Moquette weaving.

In the so-called Axminste'r loom, spools of yarns are brought into Weaving position, one for each row of' pile loops or picksv of pile, said spools ibeing carefully wound in accordance with the requirements of the pattern,all as wellknown inthis art. Accordingly, this featureof my invention resides in providing means as hereinafter claimed for knotting or positively interlocking in the form of an oriental knot the pile yarns as they are brought -around by the Axminster spools. Still referring to this feature. the invention is new in providing means for lmottingfthepile threads around the Warp threads at one forward movement. Also, the weaving is accomplished without removing the spools from the carrier chain.

My invention, however, in its broader aspects, is not limited to the utilization of Axminster spools, but includes knot-form ing mechanism for coiling a color yarn about two ground warp'threads to form an oriental knot, in connection with means for supporting` the ground warp threads for weaving, said 'two `mechanisms containing means for forming the bends for said knot inthe body of the color yarn back from and independent of the ends ofisaid yarn.

My invention is also new in providing, in connection with the aforesaid, mea-ns for positively holding 'the'color yarn on both sides lof.tlxe body portion Where the knot is V.being While fsa'd knot :is being fthus formed. Preferably I lay the color yarn lengthwise of two approximatelyA parallel ground warp :threads and provide. mechanism to move said color yarn to the fell and sin'niltanecusly'coil the same about said two ground warp threads in oriental-knot formation.

A. further advantage of my invention re-V sides in amfcmplishing the knotting operation with one weaving movement, and also preferably the entire row transversely of the loom is woven'or knotted simultaneously,`

and preferably without stopping the loom between the knotting operation and the bind` ingoperation. Preferably also each row of piles is held by its endsl at the fell and shea-red evenly as-it is woven.

Among the further novel features of my invention are the provision of tubular holdersthrough which -the threads pass and means for shifting said holdersI and thereby shifting the threads in accordance with the shedding and other weaving requirements, a knot positioner to move the knot vto the fell (said .positioner being preferably the tube of-the spool, -in the preferred Axminster-spool embodiment of my invention).

Various other features of my invention will be. referred to and fully described in the following detaileddescription, taken with reference to theaccompanying drawings, in which l have shown the preferred embodiment of my invention above mentioned.

in the drawings, Figures 1 and 2 are'longitudinal sectional views. (parts being broken away) of my loom, Fig. l showing the lower part and Fig. 2 the upper part thereof; Fig. is a sectional detail' of the knot-forminr ortion of the mechanismshov'n in Fig. l, considerably enlarged; Figs.

Mounted in suitable end frames l, 2 at the front of the loom is any usual kind of' take-up mechanism 3, 4, 5, G, 7, 8, 9, 10,

11,12, 13, guide roll 14', and breast. beam 1.5, and at the rear end of the loom is a usual warp beam 16 and Whip roll 17 for delivering the ground warp threads 18. The shuttle mechanism may be of any usual or preferred kind and hence, with various other features of the loom, is not shown in elaborate detail, the shuttle 15) (for laying binder `filling a) being herein shown as mounted on a usual lay 9.() supported on lay swords 21 fast on a rocker sha tt 22 piv oted inthe end frames and actuated by usual links 23, arms Q4, rock shaft 25, cam lever 2li, and cam 27 on the cam shaft 28. lll/bile the color yarns o may be supplied from any suitable source, when considering my invention in its broader aspects, 1 prefer and therefore have shown the supply of color yarns as derived from Axminster spools, which, it will be understood, are provided with the various con'iplements of color yarns required according to the pattern. The spool carrier chain (or, more properly, chains) 29, carrying a series of spools 30, passes over sprocket wheels 31 at the lower end of a swinging frame 32 pivoted at. 33 on the forward end of av top horizontal frame 34 fast on a rock shaft' journaled in the lupper portions 36 of the end frames 1, 2, Said chain is guided over guide sprockets B7 and is driven by a sprocket.

chain 3F? passing over sprocket wheels 3i) and 40. the latter being loose on the shaft 3.5 and immovably connected with a star wheel 41 operated by a. pin wheel 42 tast. on a shat't 43 journaled in a bearing 44 (Fig. (i) and itself actuated by. a sprocket wheel 45, chain 46 and sprocket wheel 4i on the cam shaft 9.8. As herein shown, in this preferred embodinient. ot' nl v invention, the twisting or ceiling ot the previously selected and wound color yarns around the ground warp threads is accomplished as the color yarns from the spools `are being moved forward tothe fell. This ceiling or twisting takes place back from' the free ends of said color. yarns, as distinguished, for instance, trom leading the free ends around the ground warp threads.

v Among the broadly novel features oi my invention, which makes the mechanism extremely simple, efiicient, and practical is the provision otl means i'or accomplishing this ceiling or knotting ot' the color yarn about the ground warp threads by passing the yarn between the two warp threads with which it is to be knotted and then ceilingv it around said threads entirely hack from the trre endoi' the color yarn while the ,latter is still intact with the supply body, as dis tinguished from moving the i'ree end thereot around or about the ground 'Mvarp threads or weaving with a severed 'tiragmeut of yarn. In other words, while the color yarn is held at its two ends (one end in nippers, as will ]')rcsently be described. and the other end upon the spool), l put the coils or twists' into it between said ends, which results in its being knotted properly about the ground warp threads. Preferably this is accomplished while the two ground farp threads with which it is to be knotted are held stationary, and this holding oi the two warp threads stationary in suoli a. manner that, they can cooperate with the above mentioned movement ofA the color thread to produce the desired oriental-knot weave constitutes a second broadly'novel feature of the invention. 'lhe preferred means for holding the ground warp threads stationary in such a manner as to produce, in connection withv the forwardly drawn -color yarn, a coiling or twistingl ot' the latnor-ases coiled about each other in the manner required to form the Persian knotv (as shown inthe particular species therein).

The ground warp threads remain stationary, and all the ceiling movement takes place entirely back from the tree end ot said color'ya-rn, and this is accomplished by providing such holding means for the pair of ground warp threads with which the color yarn is to be knotted that said ground warp threads are crossed over each other between the two points where the edler yarn passes between them, said two ground warp threads having a continuous space between tl-tem, however, which permits the color yarn to have free ceiling movement. lengthwise otl Said two. ground warp threads as its two portions which project on the same side of the ground Warp threads are moved together to form the tutt-ends of-tho Persian or other oriental knot. rThis holding` means tor the Warp threads is herein shown as a 'needlelike device or tubular guide holder pro.'irled with a tortuous passage extending a outlicient distance to carry one t-hread laterally in one direction while theV other thread is carried by a similar device laterallyin the opposite direction' to provide between them an opcnong for the passage of the color yarn between the two ground warp threads which are thus held laterally apart by said needlelike devices, said two holders or needle-lille devices carrying the ground warp threads in opposite direitions at their delivery ends so that said ground warp threads extend therefrom to the-tell substantially parallel to each other, but are held in crossed-owipcsition by said two holding devices bctween their laterally deflected or separated point where the color `yarn is first passed through and the point where the ground warp threads emerge from or leave the two holding devices toward the `tell. 'lhis construction is best. shown in Figs. .tl-ll and lf3-20, where itfwill he seen that the holders 4S, 49 are arrangef'l in pairs, each `having a. deflected upper part to provide an opening 50 between them and having their upper delivery ends 5l., 52 converged. In Fig. 19 the same emistruction is shown excepting that the lower part ot' each holder is in line with the upper or delivery end of the other holder of the same pair so that *the warp threads reach the fell in different order from that in which they leave the warp roll.

- As shown in Figs. 9-11 (and Figs. lr6-20),

for instance, each holder is on the same side of its pair as its own upper or delivery end, so that the warp threads reach the fell in the same relative position that they leave the warp roll. The warp threads 18 enter or are engaged and held in alinement with the tortuous passage of the holding devices at any -poirit'helow the opening 50, herein shown as below a transverse guide beam 0rmembero, wheresaid needle-like devices are provided witha curved projecting throat 5t for facilitating the easy smooth entrance, of the thread, this throat project-ing rearwardly in line. with the whip roll 17. The alternate holders are mounted to more ver ti allyY with relation to the others for the double purpose of accomplishing the shedding movement and to get out of the way of certain other .mowing parts of the mechanism, and accortilingly the yarn holders 48 are mmsnted (see Figs. l, 24, and 271) in a, terticall)v slidinglitter or cross bar 55 and the holders -l-fl in a similar cross bar 56 actuated respertivelv by links :37, 58, arms 55?, (lt), rock sha 'tts (3l, 62, and cranks or cam' Vas best shown in Fig. 7, and pointed or pinched to a. relativelyv narrow edge as indicati-,d at lf2, in side elevation Fig. 7, and in rear eleration Fig. S, so that they may [ind their way and pass through the opening 50 l'wtwetm the tobliquely bent upper ends ot the holders at!) more readily. Also. theT are so mounted with reference to the thread luildffrs-i ltd, 49 that they pass diagonally acrrss the corner which is formed by the upper ends ol said holders and the outgoing warp threads, as clearly shown in Figs. l. and 3. The pinched end or projecting corner o'l the tube 7l also serves to'prevent the contained yarn :trom getting accidentally pcsitioned at that side or edge ot: the tube, or in other words the yarn is con'ilielled to project 'from the middle or lower odge ot' the tube opposite said pinched edge, so that when the tube enters between the holders, this being facilitated as' stated by the pinched edge or projecting corner, the projecting yarn is caught and deflected or brushed downwardly around the lower corner by the warp threads as soon as the free end et' the tube enters between said warp threads in its forward ,movement These tubes are secured in usual'mai'iuer to a cross bar 7? of a carrying frame, but the latter (litters trom .the usual tube frame in providing a pivotal connection with the chain carrier, said pivot being` herein shown as consisting of a screw 74 passed loosely through the supporting plate 75 `and threaded into a depending arm 7G of the support.

The supports 76 (one at each end of the tube frame) have inwardly projecting studs 77 at their lower ends to be engaged by theA slotted' upperend 781 @fait actuatorv arm 79.

ne sliding litters 55, 5G are guided in rocked by a shaft mounted at its ends in slides 81 vertically movable in guideways 82 in the end frames by links 83, Fig. 28, levers 84. rock shaft. 85, and cani lever or crank 86 whose roll 87 travels in a path cam 88 on the shaft 28. movement is given to the. actuator arm 79 by links 89, Fiff. 31, levers 90, rock shaft 01, cam crank 92 and cam 93. The parts 75 and 7 6 are normally held in the positions shown in Figs. 7 and 8 by a spring 94; on

the part 76 whose bent frei` end (see Fig. 8) then occupies a notch or recess in the lower end of the part 75 (sce Figs. 7 and 8), a lug or lip 95 on said part 75 acting as a stop to render it impossible for the tubes to turn back too far and serving also to hold the tubes rigid when subsequently positioning the knots at the fell, and the. end supports, of which the cud portions 70 are parts, are bent laterally at their upper ends 9o and thence downwardly atdl', and again laterally at 98, where they :fue fastened to the frame 73, thereby providing vertical spaces 99 to receive the wedge-shaped ends' 100 of spool positioners 101. Figs. 3, et, and 30, mounted to slide in slideways 102 and operated by rods 1.03, levers 104, rock shaft 1,05 and a. Cam lever or crank 10G whose roll 107 travels in a. path cam 108 on the cam shaft 28. Thus, when the spool of previously selected yarn arrives at its operative position or lowest. point of travel, as shown in Figs. 1 and 3, the j'iositioners 101 move forward, thereby entering the spaces or slots 99. engaging the vertical ends 07 and thereby shoving the spool one way or the other into absolutely correct position so that its tubes 72 are brought into accurate alinement with the openings 50 of the holders 4-8, 49. The actuator arms '79 then swing the. tubes on their pivots 711 from the normal dotted position, Fig. 3. to the full line position. Fig. 3, and` while. this moven'ieut is taking place, the nippers are .coming forward to engage the free varn-ends which are projecting from the forward ends of said tubes. The nippers are herein shown as comprising a. movable jaw 10.0 pivoted at its ends at 110 on hangers .1.11. and a relatively stationary jaw 112 carried by the lower ends of said hangers 111. The yarneugaging edges of these two jaws are interlocked so as to bend the yarns and prevent their accidentally drawing outy the movable jaw being shown as provided with a longitudinal groove or recess 113 to cooperate- With a ridge or projecting' lipllllon the stationary jaw. This nipper is direetedin its movements by slides 115 moving in guide slots 116 and actuated by adjustable links '117, Fig. 26, rocker arms 118, rock shaftI Forward and back thevengagemeut of a tail piece or forwardly and upwardly projecting end 123 with the lower cam edge 1211 of a cani plate. or opening device guided in vertical movements by a slide 126 and a guide slot 27 and actuated by a rod. 128, Fig. 29, lever 129, shaft or stud 130, cam lever 131, and cam 132. The nippel' moves rearward with its jaws held open by said cam until said jaws embrace the freeends of tbe yarns which have been put through the openings 50 of the warp thread holders and np through the parallel strands of warp threads to the position shown in Fig. 3, whereupon the nippelA jaws are releasedby the cam due to the combined upward movement of said cam and rearward movement of the nippers, thereby firmly engaging and holding all the color-yarn ends. .lust as this takes place, the tubes begin swinging back again from the full line position, Fig. 3, toward their dotted line position. '.lo prevent drawing out an undue, length of stral'id or tuft yarn from the tubes, the nippers continue their rearward move-- ment until the tubes have approximately reached their said dotted position, Fig. 3, said nippers being then in the position shown in Fig. 18, where `they remain or dwell during certain succeeding movements of the tubes. The tubes, having reached their dotted line position, Fig. 3, are then raised so as to lift the color yarns or pile threads. and at the same time the holders 48, 49 are lowered (having been in raised position during the passage therethrough of said color yarns to the nippers), and when the raising'oi. the tubes has lifted the yarns above Isaid holders sulciently to permit them to be moved forward, the tubes are swung forward, preferably by swinging the adjacent end of the. chain forward. Said lifting operation is accomplished by a. cam 132%, Fig. 32, cani lever 134, roejt shaft 135, arms 180, links 13", and levers 38, see also Figs. 1 and 2. rlheselevers are fastI on the rock shaft 35 towhich the frame 34 is secured, which is provided at its rearwardly projecting end or eiitension 139 with counterbalanee weights 1410 for giving easy movenient. '.l`he cam 1.33 has an additional. lifting place 141 in its cam path for giving the chain an eXtra lift at the moment when the next spool is to be brought forward into simultaneously formed by the cooperating novarese action of the warp-thread holders 48, 49), said tubes thus constituting one form of knot positioner and serving to detlect or slide the color yarns (whose forward ends are held by the nipper) into coiled position vwith relation to the parallel strands 'of ground warp threads adjacent the fell. lVhen the free ends of the color yarns are first grabbed by the clamp or nipper and the,

tubes 71 are drawn baci( from full line position to dotted line position, Fig. 3, the color yarns extend straight back lengthwise of the loom with their forward ends extending between the raised parallel strands ofwarp threads upward to the nipperl or clamp., However, as `the tubes rise, thereby lifting the rear portions of said color yarns, said color yarns are coiled about said ground warp threads, the front portion of each color yarn being detiectedin one direction by the bent upper end of the warp-thread holder 48 and the portion of said color yarn immediately therebehind being deflected in the opposite direction by the oppositely bent upper end of the holder 49, so that when the tube has linally raised said color yarn entirely above said holders and then moves forward, the desired two,l coils orbends of the color yarn around the two warp threads have been formed as shown in Fig. 15, the

successive ceiling movements being indicated in Figs. 1S, 19, Q0. These coils 0i' partially lformed knot are slid forward to the fell by the continued forward movement of the tube or knot positioner. At the same time the clamp or nippel' is moving in the same di rection, thereby drawing forward the free end of the knotted color yarn. At. the saine time the lay lnoforward and its comb 148 beats up the tufted knot. which has been tied, and the shearing mechanism also operates. The'shearing n'iechanisin comprises. a shear blade 149 having a cutting edge 150 which is moved forward to cooperate with the npper rear edge 151 of the n'lovable nippel' jaw 109, said edges 150 and 151 constituting the two shearing edges of the severing mechanism. yln order that the knotted tufts of color yarn may not spring ontof place until bound in by the binder threafgls, l provide holding means. -Dne end of each color yarn is held in place by the nippers as already explained, and the other end is likewise held by nippexlike devices, herein shown as formed integrallyv or as a part of the shearing mechanism, although it will be nnderstood that the two functions are scimmie and may be carried ont by separate mechanisms instead of by one'mechanism as herein shown.- Just below the shear edge 150, l provide a shoulder to copcrate with a notch or recess 153 adjacent the shear edge 151 to catch the'yarn just before it. is severed and then bend and clamp the severed yarn immovably until after the shuttle 19 has laid in thc binder filling. The blade 149 is. carried by end slide blocks 154 in guideways 1535 by adjustable links 156, Figs. 1 and 3, actuated by levers 157, rock shaft 158, cam lever 159 and cam 1GO.

The operation of the loom is as follows: The ground warp threads -18 are delivered from the warp beam 1G over a usual whip roll 17 to the take-np mechanism at the front of the loom. being deliected in pairs at the weaving region so as to form the openings 50 for the passage of the color yarns, by being` passed through the ground-warp-thread holders or carrying and colorfthreadtwisling devices 4S, 49, passing therethrough from the entrance throats 54 up through the tubularportions of the holders to and ont at the crossed delivery ends 51, 52 respectively, and thence preferably parallel to the fell, and, in the completed fabric, over the breast beam. to the take-up mechanism. Viewing my invention from a broad standpoint, the color yarns may be supplied by any suitable mechanism, being herein shown as delivered from the spools 30 through the tubes 71, each spool and its-tubes being supplied with the complement of'colors required according to the patternv being woven. These spools and tubes are brought forward by the spool-carrying chain and its operating.i mechanism in the manner well known inA A'Xminster looms, whereby the particularcolor yarns are delivered in weaving position and then knotted individually about the warp threads in oriental knots.

When the pin-wheel mechanism 41, 4Q moves the chain forward so as to bring the required spool 3() into weaving position at the lower end of` the frame 32, thelatter is dropped or lowered by the levers shown in Fig. 32, said bottom spool and its tube frame being accurately positioned by the forward movement of the positioners 101 into the end slots 99 of the tube frame and the upward movement of the actuators 79 into engagement with the lugs 77 of the tube frame. At the same time the warp thread holders 48, 49 are raised to the position shown in Figs. 1 and 3, the tubes 71 then being in the dotted line position Fig. 3. The actuator' 79 is then swung forward by the mechanism shown in Fig. 31 until 'it reaches its full line position. Fig. 3. The result isthat all the color yarns of said lowerxnost spool are passed through the openings 50 of the warp threads from the rear side to the front side of the holders 48, 49 and then up between the respective pairs of warp threads where the projecting free ends of said color yarns are instantly clamped by the nipper jaws 109, 11:2 which have been moving forward in open relation until in position to grab and clamp said free ends of the color yarn as shown in Fig. 3. Thereupon the tubes are swung back again by the actuators 79 and preferably the nipper or clamping member is moved rearwardly therewith (by the mechanism shown in Fig. 26) ,so as to prevent an undue amount of color yarn being withdrawn longer than is required for the tutt or pile being woven.

. The positioners 101 having meanwhile retreated, the spool is then lifted by the rising movement of its frame 32 (actuated by the mechanism shown in Fig. 32), thereby pulling all the color yarns up to the to s ot t-he openings 50 and sliding them otl' rom the overlapped ends 51, 52 of the warp-thread holders 48, 49 by the succeeding forward swinging movement ot' the spool and its 'frame 32, whereby each color yarn is otted or coiled around its pair of warp threads, as shown in Figs. 15, 21, and 22. As the spool and its tubes continue forward, thereby positively sliding the coiled color yarns along the warp threads toward the fell, pully ing the yarns upwardly and forwardly, the

nipper at the same time pulls the other end of the knot forward, and as soon as the knot has been thus moved to the tell, the warpthread holders 48, 4S) are lowered (by the mechanisms shown in Figs. 24 and 27), thereby bringing the warp threads into correct position between the teeth of the beating-up comb 148, and then the latter beats up the knots. At the same time, the severing blade 149 is moved forward, the warpthread holders 48, 49 being down' out of the way and the spool and its tube trame and tubes being up out of the way, and simultaneously severs the knotted color threads from the tubes and holds the severed ends inclamped position. All the color yarns having now been completely knotted in place and the tuft ends of the ,knots clamped in place at the fell, the warp-thread holders 48 move down to their lowermost position and the warp-thread holders 49 move up to their uppermost position, thereby forming the desired shed for the shuttle to pass through, and then the liy shuttle is shot through, laying a strand et' binder filling. As the lay comb 148 is moving forward in its beatingup movement, the warp-thread holders 4S and 4l) are moved to their intermediate position (to facilitate the beating-up), the lay moves hack, the holders 48 move upward and the holders 49 downward, and the tiy shuttle is driven haek through the shed, layingl a second strand ol binder filling, which is then beaten. up. On the final beating movement of the lay, the shear llt) moves baek to its ,msition. lhfg. releasing the back tu l'l ends ol' the knots, and the cam plate 125 is lowered so that its edge 12-1- .engages the tail piece l2?, ot' the, nipper to open the nippel', releasing the 'liront tutt ends ol" said knots and holding the nipper jawsopen' ready 'for the next weaving operation. Meanwhile (and prelerably pist alter thc shearing operation), the spool-carrying chain 29 and its fra-me 32 have been raised, the chain advanced to bring the next color spool into lower-most position for weaving, and said frame swuh back again in place to be dropped into he position shown in' Fig. 3 ready for the next weaving operation as soon as the sheai 149 has been moved back out of the way.

While, as already stated, my invention is broadly new in many respects and therefore is not to b e restricted to the particular mechanism herein shown, and particularly to the Apm'iinSter-spml type of Color selecting mechanism, it has many advantages in this latter relation. The common Axminster loom delivers the tuft yarns from the spool around the weft hreads, whereas my invention not only delivers the tuft yarns around the warp threads, but delivers each tutt section or piece ot' tutt yarn around two warp threads, thereby showing the. pattern on the back side. The chief advantage, however, is that my mechanism ties the tufts into the carpet or rug vimniovably, as distinguished from the usual Axminster weave, in which each Jluft yarn is simply bent around one holding strand in an open-U shape. Also,

'by my invention, the knottingis aecomplished at one continuous operation around both warp threads and the knotproduced .is the'oriental knot, which is well recognized as the best. Not only is the pattern shown correctly on the back et' the goods, but the baek is smoothA` even, pliable or soft, and the knots are praeticall y immovable. A t'urther advantage resides in thefact that the spools and tubes are not removed from the chain in the course of the' weaving as has heretofore been the custom in Axminster looms. A 'further advantage of my invention is that, although weaving an orientalknot fabric, it. utilizes to a large extent the equipment at. present found in the setting` spooling, and drawing-in departments of Axminster mills. irrespective ot whether the pattern yarns are provided by means of spools or other pattern-providing mechanism, the invention provides means for lthe continuous \\'eaving` of successive rows of knotted and eoiled piles, all the ends of each row beingl termed simultaneously Iand the weaving continuing without stoppage of the loom between the knotting operations, the entire knetling beine done by one thrust or, l'oru'ai d morena-nt as distinguir-:hed from a plurality oi luufk-aml-fortl'i movements). cach row of piles is sheared evenly as it is woven. both pile portions of the knot-timming` strands are accurately positioned in ulinenient with each other transversely et theI loom at the Atell before severing, the tutt-ends are positively held until the knots. are bound in innnovably, thereby rendering it impossible t'or the severed4 yarns to nntwist, fly, tangle, or the like or snap back the positive control of the holding' means un til' after the knotting and binding thereof are completed.
